For the MQ131, the first parameter is for the heater which is already integrated into the module so you can assign it to any pin that’s not already used. The ozone gas sensor we are using is the black bakelite low concentration version so we indicate it on the third parameter. The 10000 is the load resistance. Lastly, we initialize the variable buf to store incoming messages. void setup() 1 ...
